For those not on the call, this issue came up regarding small LCDs on
copiers, printers, etc., used to inform the user about machine status,
collating options, etc. They are typically monochrome backlit LCDs.
First, any provision for this would require a new subsection in the Hardware
section; I propose "2.4 If the product has visual output". Second, here is
some language for a provision:
"All electronic visual displays must have a contrast ratio of at least N:1,
as a default or as adjusted by the user."
Note that "N:1" is the placeholder in the software/web/content provisions.

Subject: [teitac-websoftware] Hardware Labels/LCD Windows
During today's Hardware teleconference I brought up that for many low vision
users the ability to read the prompts, operation touch controls for features
like number of copies, simplex/duplex, and collating, and warning messages
is very difficult because the characters are small and they lack contrast
As part of the discussion it was asked if there should be a provision in
Section 508 to address the LCD window that used to display information or
feature controls. Another question was raised regarding which subcommittee
had jurisdiction of this provision-Hardware or Web/Software.
I would propose that language be crafted that provides a minimum level of
contrast and brightness so that people with low vision would be able to
utilize products with this type of display effectively.
